[Orion] Orion mic input question

[Joe Giacobello]

Bob, I watch my Orion's transmitted audio carefully on a scope and I run 
the mike gain wide open using the TT studio mike or a Heil dual 
cartridge (4/5) mike, and I never come close to flat topping.  I have 
not actually observed the dead span between 15-100, but now that you 
bring it up, I'll take a look.

73, Joe

I have been running my Heil HC4 element with mic gain at 65 with no known ill effects, and noticed the same on the scope with it as with a two tone test signal inserted in the mic jack.  No change in rf output with mic gain set anywhere between 15 and 100.  I can vary rf power out with the power control just like on cw.
